THOMAS WILLIAMSQOF WHITE RIVER, CALIFORNIA.

PICK.

SPECIFICATION forming part of Letters Patent No. 245,684, dated August 16, 1881.

Application filed May 27, 1881.

To all whom it may concern:

Be it known that I, THOMAS WrLLrAi/rs, of White River, county of Tulare, State of California, have invented an Improvement in Picks; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to the class of picks; and it consists in a novel means of securing and adjusting the points within the head, and in a peculiar construction of said head for the reception of the points, all of which will hereinafter be more fully explained.

Referring to the accompanying drawings, Figure 1 is a section showing my invention. Fig. 2 shows the different parts separate. Fig. 3 is a modification.

Let A represent the head or stock, provided with the handle-socket B. In each end of the stock are socketsc a for the reception of the pick-points G. Apertures c c are made through the inner walls of these sockets, at their tops or inner sides, which open into an inclined groove, D, in the inner end of the stock. These grooves or channels are inclined upwardly toward the middle of the stock, as shown. A transverse rib or flange, E, is provided in these grooves. This rib may be formed with the stock, or may consist of a bolt or pin, it preferable, so that it maybe taken out for the purpose of substitution, or to allow the key to be removed, as hereinafter shown.

F F are the locking keys or Wedges, consisting of'a flattened stripinclined upon its upper side, and having a head, 6, for convenience in handling. The under or flat side of the key is provided with a transverse groove or notch, i, in which, when the key is inserted through the sockets C and groove D, the rib or flange E fits.

Ifpreferable, the keys F F may have a flange or rib on their ends to fit into a notch in the ends of the grooves D.

The points 0 are not as wide as the sockets a a are long, and consequently do not fill said sockets, but leave a space between their inner sides and the inner wall of the sockets a a. Through this space the keys F F pass.

(No model.)

.To secure the points in the stock they are inserted in the sockets to a, and the lockingwedges F F are pushed in, passing through the sockets and the inner openings, 0 0, into the groove D, their transverse notches or grooves i fitting over the ribs E, and thus securing them. On account of their wedge shape they tit tightly and hold the points well in place. When the pick is used the keys or wedges F F cannot loosen or slip out, being held by the rib E.

'When the points have to be removed the end of the keys can be raised sufficiently to clear the ribs E, or when the rib is removable it can be taken out and the keys withdrawn. This construction enables me to adjust the points as desired. They can be pushed in the entire depth of the sockets a a, or only partially therein, and wherever set the keys or wedges will hold them securely in the sockets.

This mode of securing and adjusting the points is simple and effective. The lockingkeys are not in the way, and the stock is easily made.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A pick consisting of the stock A, having end sockets, a a, in the rear of which are the apertures c c, and having inclined grooves or channels D, with the transverse rib E, the pick-points (J O, and locking keys or wedges F F, having a transverse groove, 27, when combined and arranged substantially as herein described.

2. The pick head or stock A, having a handle-socket, B, and end sockets, a a, and inclined grooves or channels D, having an open connection, 0 c, with said sockets a a, and provided with a transverse rib or flange, E, substantially as herein described.

In witness whereof I have hereunto set my hand.
